The Disturbing Power stone of Cheng Jesteroff
The Disturbing Power stone of Cheng Jesteroff is a 186 years old piece made by Cheng Jesteroff, a mage living in Osaka.

It is engraved with asian patterns and some symbols pertaining to Shinto.
This piece doesn't exist, but as a legend. It is said that in the year 1933, Mai Jesteroff, the owner, made use of it in Osaka to empower the Jesteroff family. Now it is lost, or broken, we will never know.
